It may leak memory when two threads try to initialize the static object at the same time but this should be acceptable since each static object is only initialized once per session. <p><p>Definition at line <a class="el" href="misc_8h-source.html#l00104">104</a> of file <a class="el" href="misc_8h-source.html">misc.h</a>.<table border="0" cellpadding="0" cellspacing="0"><tr><td></td></tr><tr><td colspan="2"><br><h2>Public Member Functions</h2></td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="864479413a63f1752a16981a4819a123"></a><!-- doxytag: member="Singleton::Singleton" ref="864479413a63f1752a16981a4819a123" args="(F objectFactory=F())" --> </td><td class="memItemRight" valign="bottom"><a class="el" href="class_singleton.html#864479413a63f1752a16981a4819a123">Singleton</a> (F objectFactory=F())</td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top"><a class="anchor" name="b7f2a97041b5939110c5bde9cfd41161"></a><!-- doxytag: member="Singleton::Ref" ref="b7f2a97041b5939110c5bde9cfd41161" args="(...) const " -->const T & </td><td class="memItemRight" valign="bottom"><a class="el" href="class_singleton.html#b7f2a97041b5939110c5bde9cfd41161">Ref</a> (...) const </td></tr></table><hr>The documentation for this class was generated from the following file:<ul><li><a class="el" href="misc_8h-source.html">misc.h</a></ul><hr size="1"><address style="text-align: right;"><small>Generated on Fri Jun 1 11:11:49 2007 for Crypto++ by <a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.5.2 </small></address></body></html>⌨️ 快捷键说明
